Regarding the RFC tag. Is that for the API part? If so I think that part looks good. But it would be nice to get feedback from users who are expected to use this API as well. |
I can drop the RFC tag then, I was hoping to get more feedback but it looks like either there were no comments or people were busy with something else. |
@aescolar @Rasmus-Abildgren-Bose @carlescufi Any comments on the proposed API changes? |
|
I'm currently too busy to do a full review but have had a look at the API. I see no problem with these changes. |
|
@joerchan patches have been updated to address your comments. |

@joerchan Patches have been updated, EATT is now marked as experimental. |
|
@joerchan can you please test this on a complex application? |
Preferable against something that implements EATT already like BlueZ, but you will need to update the enable the kernel parts if you want to test ecred procedures as otherwise it connects L2CAP channel by channel, that said the features is marked as experimental exactly to give people the opportunity to test this themselves. |
|
@Vudentz My main concern was regression into ATT since some of the refactoring touches on common code. We have tested the nrf_desktop application in NCS with these changes to check for regressions. We haven't found any issues. I don't have anything to test with for the new features, so I will just go over the latest changes. |
I though the reason to add EDTT as part of CI was to extensively test ATT already, anyway now I have to resolve the conflicts you introduced with changes to the documentation which could have been avoided by just waiting this set to go in. |
This introduces new Enhanced Credit Based Flow Control PDUs and related definitions which were introduced in 5.2. Signed-off-by: Luiz Augusto von Dentz <[email protected]>
This replaces the use of tabs with spaces to align defines. Signed-off-by: Luiz Augusto von Dentz <[email protected]>
This adds the initial implementation of ECRED mode which can connect up to 5 channels simultaneously and is required by EATT. Signed-off-by: Luiz Augusto von Dentz <[email protected]>
This leaves only channels on the dynamic range to be offloaded to the system queue so ATT and EATT handling are handling in the same context. Signed-off-by: Luiz Augusto von Dentz <[email protected]>
This adds a callback to indicate when the stack has released all references to a given channel so the owner free up any resources associated with that. This is requires since EATT channels cannot rely on the destroy callback as it does not use a fixed channel like ATT. Signed-off-by: Luiz Augusto von Dentz <[email protected]>
This adds the definitions for Enhanced ATT along with new PDUs and UUIDs introduced in 5.2. Signed-off-by: Luiz Augusto von Dentz <[email protected]>
This adds support for EATT bearer which was introduced in 5.2, they work as extra channels to have GATT traffic, at the moment it is completely transparent to application when they are in use since the allocation happens automatically. Signed-off-by: Luiz Augusto von Dentz <[email protected]>
This adds support for ATT_MULTIPLE_HANDLE_VALUE_NTF, ATT_READ_MULTIPLE_VARIABLE_REQ and ATT_READ_MULTIPLE_VARIABLE_RSP. Signed-off-by: Luiz Augusto von Dentz <[email protected]>
This enables BT_EATT for shell samples so it can be build test by CI and gives user the ability of test it using shell commands. Signed-off-by: Luiz Augusto von Dentz <[email protected]>
This adds a new flag to track if the L2CAP channel is pending waiting for encryption to be changed to resume connecting. Signed-off-by: Luiz Augusto von Dentz <[email protected]>

@Vudentz nrf_desktop is a HID mouse application. It has caught many regressions earlier which is why I wanted to test it now as well. EDTT test cases are good, but they test one thing at a time and are mostly functional test-cases. Some stress-testing is good as well. This is looking good to me. I only have the one question. |
This add support for for the following features:
